<P>PROBLEM TO BE SOLVED: To shorten the time from starting under low temperature environment to the start of normal operation without increasing power consumption of a secondary battery and to keep acceleration performance equal to that before mounting an air cylinder without increasing the output of the fuel cell. <P>SOLUTION: The time requested by normal operation is shortened by switching over compressed air of the air cylinder 17 to the secondary side of an air compressor 3 at low temperature starting and supplying regenerative electric power in driving the air compressor 3 as an expansion device and electric power of a power auxiliary device 18 to a heater. By supplying the compressed air of the air cylinder 17 to the primary side of the air compressor 3 in heavy load running, compression work load requested to the air compressor 3 is reduced to reduce a load, and the maximum output performance requested to a fuel cell 1 is restrained. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
